Replace
the resistance box with a light bulb and repeat the experiment.
Keep other inputs the same but change the following conditions:
frequency = 0.1 Hz, recording rate = 50 samp/s (sample per second).
Click the MON icon to test whether you get a positive result.
You may need to wait for about 30 seconds.

Describe what
happens to the light bulb after you click the MON icon.

Is the slope
of the graph straight? If not, describe the change of the slope.

What is the relationship
between the slope of the graph and the brightness of the light bulb?

Hence, how is
the resistance of the light bulb affected by the temperature?

Increase the
Frequency from 0.1 Hz to 10 Hz. What is the change in the slope?
